How Newton County floods

Flash flooding from severe storms dominates the flood risk in Newton County, accounting for 58 of the 66 recorded flood events over the last 30 years, alongside occasional tropical storms and hurricanes. Recent events illustrate this pattern, including severe thunderstorms that developed overnight and moved across the area on March 15, 2025, as well as training heavy thunderstorms that produced flash flooding along the Interstate 20 corridor on March 8, 2024.

National Flood Insurance Program claims data shows payouts across multiple zones. Zone A properties recorded 4 claims with an average payout of $18,421 and an average recorded water depth of 7 inches. Zone UNKNOWN recorded 4 claims with an average payout of $9,431 and an average water depth of 3 inches. Unshaded Zone X properties recorded 3 claims averaging $12,402 with an average water depth of 5 inches, while Zone X recorded 1 claim with an average payout of $2,801 and an average water depth of 33 inches.

Homeowners, real estate agents, and journalists should pay the most attention to properties in Zone A and unshaded Zone X areas, which have experienced repeat claims and notable water depths during heavy rainfall events.

From the storm reports

Flash Flood · Mar 15, 2025. Isolated severe thunderstorms developed across portions of Mississippi in the overnight hours of March 14th. Coverage of severe storms increased into the morning of the 15th before a squall line developed and moved across the area.

Flash Flood · Mar 8, 2024. Training of heavy thunderstorms produced flash flooding across central Mississippi and the Interstate 20 corridor.

Flash Flood · Jun 19, 2023. An upper-level shortwave trough moving east through the Central Plains initiated a few clusters of thunderstorms that spread into Mississippi during the morning of June 18th. With an unstable air mass and strong jet stream over the region, these storms became severe and produced hail and damaging wind through the morning. An additional round of severe storms developed during the evening of the 18th and into the mo…

Flash Flood · Aug 24, 2022. A low pressure system spinning over northern Louisiana and southern Arkansas brought several rounds of showers and thunderstorms producing heavy rain to Mississippi August 24th through 25th. This resulted in widespread flooding of roads, homes, and businesses around the state.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Newton County

If a building in Newton County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
